For an organization that didn't pardon Galileo until 1992, the Vatican is surprisingly open with its use of technology. The Pope, or someone acting on his behalf, keeps up a regular Twitter feed (in six different languages, obviously).

The app in question, called "Confessions: A Roman Catholic App" reminds the pious of the ten commandments and allows you to check off the sins you've committed. It costs $1.99, and will then generate a script of sorts outlining your confessions.

This, however, is only prep work; instead of sending the list to a priest, you actually have to go tell him yourself. Personally, while I have no interest in actually confessing, I wouldn't mind getting a look at that list of sins.
